Ibanez AFR4WAP-NTF Affirma 4 String Bass Guitar In Natural Flat

Elegant, Ergonomic & Versatile

Written by

Elliot Stent

Almost 30 years after its introduction, the mighty Affirma bass is back and leading Ibanez’s 2019 bass lineup. With a quirky yet elegant body shape, the Affirma originally represented Ibanez’s break into the high-end bass market, with a model that not only provided excellent tones but optimal playing comfort too.

The unique Rolf Spuler design remains intact, and has been proudly revived with some thoughtful updates. This first-class instrument will suit the most discerning of bassists in the 21st Century, especially with its ergonomic design.


The Ibanez AFR-4 Affirma bass’ body is constructed from Walnut, a dense tonewood that yields a warm sound with a tight response. This gives notes a rounded tone and an immediate attack, whether you’re playing finger-style of with a plectrum. A noteworthy feature on the body is the carved-out channel, which serves as a useful thumb rest at multiple positions.

The Affirma’s body is paired with a 3-piece Maple neck, accentuating the treble response and sensitivity of the instrument even more. Reinforced with graphite rods, these ensure minimal neck movement in differing climates, so that you’ll almost never have to tweak the truss rod. If you do though, the adjustment has been thoughtfully placed at the bottom of the neck for super-easy access.

With an Ebony fingerboard, this sleek material not only feels smooth under the fingers but also adds some extra mid-range warmth, while tightening the overall sound of the bass. Fitted with medium-sized frets to strike the perfect balance between traditional and modern, these have been given Ibanez’s premium fret edge treatment to guarantee ultimate comfort when you’re playing long sets.

Electronics & Hardware

The Ibanez ARF-4 Affirma is installed with a single Bartolini® X44JX pickup, a split-coil design that delivers a deep yet vibrant tone. With its combination of the piezo and magnetic pickup, you can attain articulate and dynamic tones, with the Ibanez 2-band EQ allowing you to further sculpt the perfect sounds.

The specially-designed AeroSilk MR5 bridge features unique saddles, designed to work in concert with the piezo pickups and enhance the acoustic "stand-up" quality of the sound. Also allowing for extreme intonation adjustments, each isolated bridge is securely locked down to the body for maximum vibration transfer without interference.
